Applic'a-tien filed ma 1, 1926. Serial 1%. 106,095.

This invention relates to brushes, and more particularly to hair brushes, .and has for its object, to improve the sanitary condition of the brush, and to provide'ab-rush frame adapted to maintain and hold within the frame structure, brush carrying removable units, which are interchangeable, one with the other, in any position Within the brush, and the terminal ends of the brush carrying frame being uniform in shape.

A )phcant now has a pendingjapplication in t he United States Patent Office, filed March 5, 1925, Serial Number 13,170, the ob-. ject of which is similar tothe application filed herewith. Y

Further objects of invention, consists in new, novel, and useful means for maintaining the individual unit brush members, in relation with each other, and in fixed position within the frame. v

A further object ofv my invention, consists of the making of'the same of few parts, and that are adapted-for general use in brushes, as well as in'hair brushes, and one that may be assembled and disassembled by those inexperienced in mechanical things.

With these and incidental objects in view,

the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is here? ina-ft'er shown with reference to the draw ings which accompany and form a part ofthis specification.

In the drawings z- Fig. 1 is a perspective View of the assembled brush.

Fig. 2 is a cross sectional view, taken on line 2-2 of Fig. 1, looking in the direction indicated.

Fig. 3 is a side elevation, in section, here illustrated as being disassembled.

Fig. 4: is a sectional end view, taken on line 44 of Fig. 1, looking in the direction indicated. V

Fig. 5 is a perspective view of the back closure.

Fig. 6 is a fragmentary perspective view of the mid-section of the brush, made to feature the spring member for maintaining the brush units under compression.

Fig. 7 is a perspective view of one of the brush units.

, Fig. 8 is .a cross section, taken'on line 88 of Fig. 2, looking in the direction indicated.

inner 'b'ack2, which is provided witha handle 1. This inner back is "made of thin light weight material, and to further materially reduce its weight I have provided oppositely positioned arcuate indentations as shown in Fig; 6. At the point where the inner back joins the handle '1, and spaced therefrom, I have formed 'an inwardly projecting portion 3,.the purpose of which will be explained later.

Embracing the inner back2, I provide an outer back '6. This outer back is provided with vertical side walls 12 and 13 and an in warolly turned end wall 5, and when the outer back is in position upon the inner back, as showii'in Fig. 1, and in the more detailed cross section view of Fig. 2; the inwardlyturne'd end'wall 5, and the inwardly projecting portion will each be spaced at approximately the same distance from the inner back 2. In order'to secure the outer back to the inner back, I have provided outstanding pins or projections 16, at the junction of the inner back 3 and the handle 1, and through the inner ends of the walls 12 and 13 have been formed the holes'or eyes '15, which are to fit about and embrace the pins 16. The side walls are bent slightly outward when the eyes 15 engage or disengage the pins 16. This is particularly illustrated in Fig. 4.

In my brush I prefer to use interchange able bristle carrying members 7, shown in Fig. 7. The member 7 I prefer to have constructed of light metal, or of some other nonabsorbent material, and I also prefer to have but one row of bristles on each bristle carrying member. The bristles 9 may be assembled to the member by any well known meth- 7 0d, though I use the groove method, wherein a groove 8 is formed in line with the bristle carrying holes. and a non-corrosive wire is passed along the groove, and sews or ties each tuft of bristles in its respective hole. After the bristles are in place, the groove 8 should be filled with a non-absorbent and non-corrosive material to prevent the entry of foreign matter therein. In future references to the individual bristle carrying members in this specification, I shall refer to the same as brush elements.

, Referring again to Fig. 3, a brush element 7 is shown positioned Within the inner and outer back assembly, and the inwardly projecting portion 3 and the inwardly turned end wall 5, slightly overlap the outer ends of the brush elements. As the brush elements are slightly less in vertical cross section than the width between the inwardly projecting portion 3 and inwardly turned end wall 5, respectively, and the inner back 2, the brush elements will be held loosely upon the inner back, within the assembly, by means of the elements 3 and 5 aforesaid. It is desirable that there be no play or movement of the brush elements, and to avoid this I have provided an arcuate leaf spring 4, which is placed between the inner back 2 and the brush elements 7. This will cause the brush elements to bear upon, at their outer ends, the inwardly projecting portion 3 and the inwardly turned end wall 5, and thus movement of the brush elements will be eliminated.

lVhile in Figs. 1 and 3, I have shown the brush backs carrying five rows'o'f brush ele ments, this number is merely for the purpose of illustration, and inasmuch as the width of the backs, or of the bristle elements may be altered, it will be seenthat the number of brush elem ents is optional.

lVhile the form of mechanism herein shown and described is admirably adapted to "fulfill the objects primarily stated, it is to be understood that it is not intended to con i'ine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.

W hat I claim is v i 1. A. hair brush embodying an inner back, including a handle; an outer back embracing the inner back; an inwardly turned'end wall formed upon the outer back; an inwardly projecting portion formed on the inner back; one or more brush elements disposed upon said inner back and having the ends thereof positioned below the inwardly turned end wall and the inwardly projecting portion aforesaid; and a yielding element disposed between said brush elements and said inner back, andcausing the ends of said brush elements to engage, the inwardly turned end wall and the inwardly projecting portion aforesaid. V

hair brush embodying an inner back, including a handle; an outer back embracing the inner-back; said outer back member being provided .vitlrvertical side walls and an iinvardly turned end wall; oppositely positioned outstanding pins formed on the inner back; an'eye "formed in theinner end of each of said walls; said eyes adapted to em.- brace said pins; an inwardly projecting portion formed on the inner'back ;'a plurality of brush elements disposed. upon said inner back and having the ends-thereof positioned below the inwardly turned end: wall and the inwardly projecting portion aforesaid; and a 'yieldable element disposedbetween said brush elements and said inner back, and causing vthefends of said brush elements to engage the inwardly turned end wall and the inwardly projecting portion aforesaid.

3. A hair brush embodying a pair of emb'racing back members; a handle provided for one of said back members; means for maintaining said back members in engagement with each other; oppositely positioned and inwardly disposed projecting portions formed on saidback members brush elements positioned between said projecting portions and said back members; and a spring element positioned between said brush elen'ients and said back members.
